Title: Two-position cleat, in particular for sailboard
IPC: B63B21/18
Filed: 1983-04-11
Abstract: The invention relates to a device which makes it possible to block one end of the small trapeze cord which serves for the use of a sailboard harness. This device makes it possible in a certain position to allow this small cord to slide, then in the other position to wedge this small cord. Passing from one position to the other takes place without releasing the wishbone. It consists of a main part: the cleat T which has on its projection 1 a hole 2 in the form of a V. The other piece is a ring B which slides onto the cylindrical part of the cleat 3 and comprises a projection 4 pierced by an orifice 5 for passage of the small cord. Rotation of the ring B draws the small cord 8 into the point of the V to block it, and conversely to unblock it.
Patent FR-2525301-A1 (FR)
Inventor: NOBUYUKI OSAWA
IPC: F16C29/06
Filed: 1983-04-14
Abstract: A guideway bearing is designed with a sliding table, an elongate guideway carrier, side plates secured at opposite ends of the sliding table, a holding part and a multiplicity of rolling balls. The sliding table has two parallel, axial running tracks having the cross-section of a pointed arch which are formed in each of the obliquely extending surfaces of an outwardly opening trapezoidal groove, and axial through holes which are formed on the rear side of the running tracks and represent passages for the balls. The guideway carrier has running tracks similar in shape to pointed arches, which are formed axially and correspond to the running tracks of the sliding table. Each of the running tracks similar in shape to a pointed arch has a narrow receiving groove at its base. The side plates comprise semicircular ball tracks which straddle the running tracks of the sliding table and the through holes corresponding to the said running tracks. Each of the semicircular ball tracks has at its base a narrow concave groove and takes the form of a recess. The holding part comprises a wire rod with a straight portion and, at opposite ends of the latter, portions bent into a semicircle. The portions bent into a semicircle are in engagement with the concave grooves in the side plates. The balls are arranged between the running tracks of the sliding table and the running tracks of the guideway carrier and in the through holes of the sliding table and the ball tracks of the side plates. The balls are chosen so that they are in four-point contact between the running tracks of the sliding table and the opposite running tracks of the guideway carrier. The sliding table is supported on the guideway carrier by four rows of balls in four-point contact. The sliding table can be moved axially by virtue of the rolling movement of the balls.
